' Application filed August 4, 1916. Serial 110. 113,155.

To all whom it may concern:

Be it known that we, WILLIAM D. RALs- TON and 'WILLIs G. RALs'roN,citizens of the United States, residing at New Marion, in the county ofRipley and State of Indiana, have invented certain new and usefulImprovements in Adjustable Curtain-Shade Brackets; and We do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to an adjustable curtain shade bracket and hasfor its primary object the provision of means whereby the device may bereadily and quickly apv plied to a window frame without the employmentof nails or screws] and which obviates the use of a tool to apply andremove the device, thereby preventing the window frame from being marredor injured.

Another object of this invention is to provide a pair of jaws adjustablyconnected together, whereby the door may be applied to window frames ofseveral sizes.

A further object of this invention is to provide a bar pivoted to one ofthe jaws and adjustably secured to the other jaw, whereby uponoperatingjhe lever, the jaws will be moved in the direction of eachother to clamp a window frame.

A still further object of this invention is to provide a slot in the barand having a plurality of teeth formed on the wall thereof to be engagedby a dog actuated by the lever, whereby upon movement of the lever, thedog will engage the teeth and draw the jaws in the direction of eachother.;

With these and other objects in view as will become more apparent as thedescription proceeds, the invention consists in certain novel featuresof construction, combination and arrangement of parts as will behereinafter more fully described and claimed.

For a complete understanding of our invention, reference is to be had tothe following description and accompanying drawing, in which Figure 1 isa fragmentary front elevation of a window frame, illustrating ourinvention applied thereto,

Fig. 2 is a vertical sectional view of an adjustable curtain shadebracket, constructed in accordance with our invention, and

Fig. 3 is a top plan view of the same.

Referringin detail to the drawing; the numeral 1 indicates the upperportion of a window frame of any desired construction, having adjustablecurtain shade brackets, constructed in accordance with our inventionsecured to each end thereof. Each of the adjustable curtain shadebrackets are identical in construction except the supporting bracketsshade roller is attached, one of the brackets being provided with theordinary slot and the other bracket with the aperture to cooperate withthe construction of the ordinary curtain shade roller. As both of theadjustable curtain shade brackets are identical in construction exceptfor the aforementioned parts, it is not deemed necessary to now describeeach of them in detail as a description of one of them applies to both.

Apair of jaws 2 and 3, each constructed from a metallic platehaving oneof its ends bent to form jaw engaging portions 4 that engage inoperation the upper and lower edges of the window frame 1. A pair ofrelatively spaced ears 5 are riveted or otherwise secured to the jaw 3and are struck up from'a single length of metal so that each of the earsare secured together by a strip 6. A bar 7 is pivoted between the ears 5as illustrated at 8, and has an elongated slot 9 therein, the lower wallof which is provided with a plurality of teeth 10,

A pair of relatively spaced ears 11 are riveted or otherwise secured tothe jaw 2 and are struck up from a single length of metal so as tosecurethe ears together as illustrated at 12. The ears 11 are providedwith either the slot or the aperture to receive the ends of the ordinarywindow shade roller and one of the ears 11 has formed thereon anextension 13 to which is pivoted an operating lever 1+1. The pivot 15 ofthe operating lever ltextends through the elongated slot 9 of the bar 7which is slidably received between the ears 11. A

plate 16 is secured to the pivot 15 and disposed upon tlie opposite sideof the bar 7 from the operating, lever 1 1 and has ecto which the endsof a curtain centrically connected thereto a dog 17, the free end ofwhich is bent at right angles to engage the teeth 10 of the bar 7 Inoperation when desiring to apply the device to a window frame, the jaws2 andv parallel relation with the bar 7, the dog 17 simultaneouslyengages one of the teeth 10 of the bar 7 and bears the bar in thedirection of the aw 2, thereby moving the jaws in the direction ofveach, other to tightly clamp the windowframe If one movement of theoperatinglever is not suflicient to tightly clamp the jaws to the windowframe, by swinging the lever upwardly, the dog 17 will be movedforwardly engaging the next adjacent notch and by downward movement ofthe lever, the bar again will bemovedin the direction of the jaw 2tightly clamping the jaws upon the window frame.

While we have shown and described the preferred embodiment of. ourinvention, it will be understood that minor changes in construction,combination and arrangement of parts. may be made without departing fromthe spirit and scope of the invention as claimed,

Haring thus described our what we claim isz- V 1. A device of thecharacter, set forth comprising apairof jaws, means for securing a shaderoller to one of the jafws, a pairv of relatively spaced ears secured tothe other jaw, a bar pivoted to said ears, and means for adjustablysecuring the bar to the other aw for movingsaid jaws in the direction ofeach other to clamp a window frame. i

2. A device of the character set forth comprising a painof jaws a pairof relainvention,

tively spaced ears secured to one of the jaws, a bar pivoted to saidears, a pair of relatively spaced ears secured to the other jaw andslidably receiving said bar, means for securing a shade roller to thesecond mentioned pair of ears, and means carried by the second mentionedears for an engagement with the bar to move the jaws in the direction ofeach other to clamp a Window frame.

3. A device of the character set forth comprising a pair of jaws, a barpivoted to one of the jaws and having an elongated slot therein, aplurality of teeth formed on the wall of the elongated slot, a pair ofrelatively spaced ears secured to the other jaw, and slidably receivingthe bar, means forsecuring a shade roller to the ears, an extensionformed on one of said ears, a lever pivoted to said extension, a platecarried" by the pivotof the lever and disposed upon the opposite side ofthe bar froin'the lever, and a dog eccentrically secured to the plateforan engagement with the teeth to move the jaws in the direction of'each other upon movement of'tlielever to clamp the aws upon a windowframe. 4

4:. A device of the character set forth comprising a pair of'jaws, apair of relasecured to the pivot and disposed upon an opposite side ofthe rodfrom the lever,and a dog eccentrically connected to the plate andadapted to engage the teeth upon operation of' the lever to move the jawsin the'direction of each other.

In testimony: whereof we our signatures in presence of two witnesses,
